Subject: [PATCH] Refactor cover art handling and improve accessibility

- Extract cover art fetching logic into a dedicated useCoverArt hook
- Replace duplicate cover art fetching code in MopidyPanel with the new hook
- Improve accessibility in App.jsx by using proper ARIA attributes (aria-selected, role="tab")
- Add Flask dependency to requirements.txt for now-playing service
- Add Content-Length limit to bandcamp-api to prevent DoS attacks
- Remove MopidyPanel.jsx.bak file
